The Integrated Physical Property Measurement System (PPMS) measures a wide range of parameters and has a wide range of applications, and the number of installations is increasing worldwide
The comprehensive physical property measurement system (PPMS) is a new type of comprehensive physical property measurement instrument based on extremely low temperature and strong magnetic field control platform, integrating electricity, magnetism, thermal and other physical property measurement technologies, and widely used in materials science, chemistry, physics and other fields.
The comprehensive physical property measurement system covers a wide range of measurement parameters, including topography characterization, AC/DC magnetic susceptibility, magnetic torque, high temperature magnetic susceptibility, critical current, differential resistance, AC/DC resistivity, magnetic resistivity, Hall coefficient, I-V characteristics, specific heat, thermal conductivity, thermoelectric coefficient, etc.
According to the "2024-2029 China Comprehensive Physical Property Measurement System (PPMS) Industry Market In-depth Research and Development Prospect Forecast Report" released by Xinsijie Industry Research Center, the comprehensive physical property measurement system has the characteristics of multiple measurement parameters, fast sweeping speed, continuous and stable temperature control, rapid and stable temperature change, etc., and the measurement objects include but are not limited to metal alloys, polymer materials, semiconductor materials, dielectric materials, magnetic materials, superconducting materials, etc., which are widely used in materials science, information science, physics, chemistry, Biology, natural sciences, geology, systems science, etc.
The comprehensive physical property measurement system was developed in the mid-90s of the 20th century by Quantum Design in the United States. Due to the full use of extremely low temperature and strong magnetic field environment, and the wide coverage of measurement parameters, the comprehensive physical property measurement system can meet the application needs of different fields and different scenarios, simplify the experimental process, and reduce the cost pressure of customers to purchase different types of scientific instruments, so the penetration rate in the global market continues to increase.
The integrated physical property measurement system works in the liquid helium temperature zone and needs to be refrigerated by liquid helium. Liquid helium is extracted from high-helium natural gas, which has small resource reserves, difficult preparation and high price. The earliest comprehensive physical property measurement system was the liquid helium filling system, which consumes a lot of liquid helium and has a high cost of use. In the late 90s, the integrated physical property measurement system was introduced as the liquid helium closed-cycle system (EverCool), and the consumption of liquid helium was greatly reduced. In 2010, the DynaCool Completely Helium-Free Integrated Physical Property Measurement System (DynaCool) was launched, and the cost of ownership was significantly reduced.
According to the news released by Quantum Design in May 2023, its comprehensive physical property measurement system has been installed nearly 2,000 sets worldwide, DynaCool has shipped 500 sets, and in China, the installed volume of comprehensive physical property measurement systems is close to 300 sets.
Industry analysts said that China's scientific research strength has made rapid progress, and the demand for comprehensive physical property measurement systems is large, while China's high-helium natural gas resource reserves are scarce, and the demand for liquid helium depends on imports, and the demand for completely non-liquid helium comprehensive physical property measurement systems is even stronger. The realization of liquid helium-free technology is to rely on the cryogenic refrigeration mechanism to cool the superconductor so that the working environment temperature of the superconductor reaches the liquid helium temperature zone and form superconductivity. The mainland government is vigorously promoting the development of low-vibration and large-capacity vascular coolers in the liquid helium temperature zone to realize the application in instruments such as liquid helium-free low-temperature and high-intensity magnetic field comprehensive physical property measuring instruments.
